Research on Aluminized Boundary of Car Lamp Parts

Abstract

Based on the aluminizing process of automobile lamps, this paper studies the masking method of tooling in the non-aluminized area for the lamp parts with complex aluminized boundary structure. First, analyze the aluminized parts in the car lights, and determine four common aluminized boundary structure models; secondly, use a microscope to observe the aluminized transition area, and analyze the aluminized parts under different masking tooling parameters (H, J, Z) through a value and b value. And then, according to the analysis results, the design method of aluminized tooling with different aluminized boundary structures is given. Finally, the effectiveness of this conclusion is verified by practical cases.
